There might had been a requirement for 24 heavy lift aircrafts to replace IL 76 in the past (not necessarily 24 x C17s back then, but the fact remains that we only ordered 10 with 6 optionals. That's why I said that the opening article confused things, since the order of 8 didin't fit to any official statement. And now with the production line getting closed, 12 is simply the max that can be sold to other customers, that might have interest. Lets see what the MoD and IAF now will decide and how many C17s will be left for them, more importantly at what costs (!!!), I hope they finally make a propper evaluation of the options and the actual requirement this time.
You are mistaken, we are talking about the C130"J", the latest varient which entered service just a few years ago and will continue to be exported for years, just that the competition now will become stronger with KC 390s, MTA, A400 and possibly XC-2s arriving on the export market. So the old C130s have nothing to do with a possible production line in India and again, the ToT limitations comes from their side and their export laws, as long as that doesn't change, there is no share of critical techs, no matter how many C130Js we would want to buy. That's even the same problem with MMRCA, LUH, or the ATGM competitions.
